Failed spark plug wires and/or ignition coils can cause intermittent misfires (rough running); the Check Engine Light may also illuminate. Diagnoses of the ignition system will be necessary to determine which components are at fault.

The car runs real rough when I step on the gas in drive. If I shift the car myself it runs better but still mis-fires
